[67.09] Acoustically Enabling a Planetarium to Function as a Classroom

T. C. Bush, M. Shepherd, T. Leishman (Brigham Young University)

Planetariums usually have poor acoustics due to their domed
ceilings. Brigham Young University recently built a
planetarium that was also intended to serve as a classroom.
Acoustical recommendations were requested and implemented in
its construction in order to make it a suitable listening
environment. The preliminary acoustical modeling,
specialized materials, and results of acoustical
measurements taken after construction are discussed to
demonstrate how this objective was achieved.
